Title: Open=end spinner opening roller assembly - is a pot-shaped unit with inner wall parallel to roller axis for simple mounting in the housing
Inventor: POHN JOHANN
IPC: D01H4/32
Filed: 1991-06-27
Abstract: Housing for the sliver opening roller, in an open-end spinner assembly, has a slit extending from the outer side to the drilling passing through the roller mounting. Two straps are on both sides, as radial extensions of the slit walls, to hold a spreader. A mounting for the opening roller bearing is on the length of the drilling. Pref. the two straps are along a length of the drilling, the slit at the drilling length, is wider than at the housing length to hold the unit, and the slit expands conically from the unit. The slit is at the section of the housing where fibres do not pass through and the outer dimensions of the pot-shaped unit and the inner dimensions of the housing are structured so that the unit is clamped by the housing when it is released by the spreader. The spreader is a release screw passing through a threaded drilling in one strap to bear against the other strap on the other side of the slit. The bearing mounting has a clamp action, next to the spreader in the straps, with the spreader at a greater radial gap from the drilling clamp than the mounting. The straps are connected to the base of the housing and the clamp can be applied by a screw passing through a drilling in one strap to engage a threaded drilling in the other strap. The spreader is at the housing end of the drilling and the clamp is at the end away from the unit. The unit has a shoulder extending into the slit. ADVANTAGE - The structure gives a pot shaped unit with an inner circumference wall parallel to the axis of the opening roller for simple assembly and dismantling in the housing.

Patent DE-4138499-A1 (DE)
Inventor: BILLER BERND DIPL ING
IPC: A01F25/13
Filed: 1991-11-22
Abstract: The invention relates to an appliance for wrapping a round bale of hay, half-hay or straw with a plastic foil. The appliance has a frame 6 and a wrapping table 31, attached to the latter, for receiving a round bale to be wrapped. The frame can be mounted on a round-bale press 21. The round bale to be wrapped is fed via a rolling grid 9 to a loading bar 11. For transferring the round bale onto the wrapping table 31, the latter is pivoted in the direction of the loading bar 11. For the transfer, the loading bar 11 and wrapping table 31 are pivoted until the wrapping table 31 is in the horizontal wrapping position. For unloading the ready-wrapped round bale, the wrapping table 31 is tilted rearwards, that is to say away from the loading bar 11. This design leads to a shorter construction and to an improved transfer of the round bale onto the wrapping table towards the wrapping position. <IMAGE>

Inventor: MATSUURA TAKASHI
IPC: F02D41/30
Filed: 1992-06-12
Abstract: An idling R.P.M. control system for a two-stroke engine sets. 58, the desired R.P.M. corresponding to a coolant temperature, calculates, 59, a deviation ( DELTA  N) between the desired R.P.M. (Ned) and engine R.P.M. (Ne), and calculates, 60, an idling correction amount (Gfa). A basic fuel injection amount (Gfs) is derived from engine speed and accelerator position detectors, 43, 51, 53 and is adjusted by the idling correction amount to provide the correct fuel injection duration. Only the amount of fuel is corrected by the use of the idling correction amount, with a fixed intake air amount. Thus a feedback control is performed in the cold state of the engine so as to hold stratified combustion favourable and to appropriately raise the engine R.P.M., so that the warming-up of the engine is promoted, and the speed thereof is stabilized. <IMAGE>
